10 Best Mini Split Ac Unit For Semi Truck 2026 in the United States

This 12V DC mini-split air conditioner offers a solid 9000 BTU cooling capacity, which is a good fit for semi-trucks, RVs, and other heavy vehicles needing reliable cooling while parked or on the road. It runs directly off the vehicle’s 12V battery without requiring the engine to be on, helping reduce fuel use and pollution during breaks. The scroll compressor provides efficient and steady cooling performance. Noise is kept low at around 35 decibels, meaning it operates quietly enough not to disturb rest or communication inside the cab.

The unit supports split system installation, which typically means better airflow and easier maintenance compared to window units, but installation may require professional help. A remote control and panel buttons allow easy adjustment of temperature and fan speeds, adding convenience on the go. The unit also has rapid cooling and a 5-level airflow system with 360° rotating outlets for even temperature distribution. On the downside, its energy efficiency rating is modest at 2 stars and a SEER of 13, so it may draw relatively more power compared to higher-efficiency models. It demands a strong vehicle battery—over 200AH—to handle the 60-70 amps current draw, which is important for users to consider to avoid battery drain.

This air conditioner is practical and convenient for truck drivers or RV owners who want a quiet, effective cooling solution powered by their vehicle battery, but it requires attention to power supply and possibly professional installation.

The Cooligo Truck Cab Air Conditioner is designed specifically for semi-trucks, RVs, and other large vehicles needing a 12V cooling solution. With a solid cooling capacity of 12,000 BTU and a strong airflow of 265 CFM, it can effectively cool areas up to 430 square feet, making it suitable for truck cabins and small living spaces. The rotary scroll compressor enhances energy efficiency and keeps noise levels low, which is important for comfortable use during long drives or rest periods. Installation as a split system requires removing an existing skylight, so some effort and proper sizing are necessary, but the system is compact and uses durable materials suitable for vehicle environments. The remote control adds convenience, allowing you to adjust settings easily.

The product claims high efficiency and fuel savings by running off a 12V power source, helping cut costs compared to traditional AC units. It also continues cooling even when the engine is off, which is a valuable feature for truckers needing rest without idling the engine. Buyers should be aware that this unit requires an outdoor component and professional installation may be needed to ensure proper setup. The limited warranty and positive customer reviews suggest reliability, but the product's weight (nearly 60 pounds) means installation might not be a quick DIY job for everyone. This AC unit represents a practical choice for semi-truck owners looking for a dedicated, energy-conscious cooling system with good power and quiet operation.

The Aspligo 12V DC Air Conditioner is a versatile mini-split AC unit designed for various vehicles, including semi-trucks, RVs, and more. Offering between 6800 to 10500 BTUs of cooling power, it promises fast and efficient cooling, making it suitable for larger vehicle cabins. One of its standout features is its low noise level, with the internal unit operating at 37 dB, ensuring a quiet environment for driving and sleeping. This is a significant advantage for long-haul drivers who need a peaceful resting environment.

The unit's energy efficiency ratio (EER) is relatively modest at 3.26, which might not be the best in the market but still provides a decent balance between performance and power consumption. However, it requires a robust power setup including a 12V 80AH or higher battery and a 1500W generator, which could be a consideration for some users. The installation is split-type, which generally allows for flexible placement but may require professional installation.

One potential drawback is that the unit does not come with refrigerant, meaning users need to purchase and add 550g of R134a refrigerant themselves, along with performing a vacuum treat. This could be an additional hassle for those who are not familiar with AC maintenance. Additionally, the unit includes modern conveniences like remote control for ease of use.
